Earthquake Resistant TechniquesIntroduction“Earthquakes do not have the ability to kill or cause damage, unlike buildings. » This is a famous quote that attempts to emphasize the need to take precautions and measures against earthquakes, especially in buildings. Earthquakes, like other natural disasters, cannot be avoided, although it is possible to minimize their impacts and effects. Like other natural calamities, earthquakes have the capacity to cause harm and harm to life and property. Two basic types of seismic waves are responsible for earthquakes (Chang and Soong, 1992). These two waves are distinguished by the speed at which each of them travels across the Earth. Primary or thrust waves travel faster and are longitudinal in nature. These waves also have the ability to pass through liquids. The slower waves are called secondary waves or shaking waves. These waves travel like light waves, although they cannot travel in liquids. Seismic waves that cause earthquake risks become more destructive when they pass through the ground and reach its surface where structures and buildings are located. When these waves reach such places, the cause is strong. ground movements that cause buildings and structures to shake and move at very high speeds. Most buildings and structures cannot withstand ground movements and as a result buildings and bridges collapse, fires, flash floods and destructive ocean waves occur and in some cases landslides of terrain occur. Densely populated areas can suffer serious injuries and even death from earthquakes. In order to take precautions, particularly in buildings, several seismic techniques must be put in place.
